DETAILED DESCRIPTION OF THE INVENTION

[0013] As shown in FIGS. 2-5, a walking frame embodied in the presentinvention is used as a support in walking by the lame, convalescents,etc.

[0014] The walking frame of the present invention comprises two frames20 and 30, two seat rods 40 and 50, and a seat 60.

[0015] The first frame 20 and the second frame 30 are basically similarin construction to each other and are formed of a first support rod 21,31, a second support rod 22, 32 and a connection rod 23, 33 forconnecting the first support rod and the second support rod. The firstsupport rod 21, 31 is provided at the bottom end with a wheel 24, 34,and at the top end with a hand grip 25, 35. The second support rod 22,32 is provided at the bottom end with a wheel 24, 34, and at the top endwith an inverted U-shaped fastening piece 201, 301 by means of which thesecond support rod 22, 32 is fastened with the first support rod 21, 31.

[0016] The first seat rod 40 and the second seat rod 50 are adjustablyfastened between the two frames 20 and 30 such that the first seat rod40 is fastened with the first support rods 21 and 31, and that thesecond seat rod 50 is fastened with the second support rods 22 and 32.

[0017] The seat 60 is fixedly mounted on the two seat rods 40 and 50.

[0018] The walking frame of the preferred embodiment of the presentinvention is characterized by the first support rods 21 and 31, thesecond support rods 22 and 32, and the two seat rods 40 and 50.

[0019] The two first support rods 21 and 31 are respectively providedwith a plurality of locating holes 211, 311, which are arranged at aninterval along the longitudinal direction of the first support rods 21and 31. Similarly, the two second support rods 22 and 32 arerespectively provided with a plurality of locating holes 222, 322, whichare arranged at an interval along the longitudinal direction of thesecond support rods 22 and 32.

[0020] The first seat rod 40 is provided with two locating seats 41which are similar in construction to each other and are provided with acircular slot 411 for receiving the seat rod, and two fastening portions412 and 413 (not shown in the drawings). The fastening portion 413 isopposite to the fastening portion 412. The fastening portions 412 and413 are provided with at least one through hole 414. The through holes414 of the fastening portions 412 and 413 are corresponding in locationto each other. The first seat rod 40 is adjustably fastened with the twofirst support rods 21 and 31 by at least two fastening members 70consisting of a bolt 701 and a nut 702. Similarly, the second seat rod50 is provided with two locating seats 51 which are similar inconstruction to each other and are provided with a circular slot 511 forreceiving the second seat rod 50, and two fastening portions 512 and 513which are opposite to each other and are provided with at least onethrough hole 514. The through holes 514 of the two fastening portions512 and 513 are corresponding in location to each other. The second seatrod 50 is adjustably fastened with the two second support rods 22 and 32by at least two fastening members 70 consisting of a bolt 702 and a nut702.

[0021] The first seat rod 40 is fastened adjustably at various levels ofthe first support rods 21 and 31 by the bolts 701 which are put throughthe through holes 414 of the locating seats 41 and any one of thelocating holes 211 and 311 of the two first support rods 21 and 31.Similarly, the second seat rod 50 is adjustably fastened at variouslevels of the second support rods 22 and 32 by another bolts 701 whichare put through the through holes 514 of the locating seats 51 of thesecond seat rod 50 and any one of the locating holes 222 and 322 of thetwo second support rods 22 and 32.
